Any shade of politics you like, so long as it’s green
...This week’s explosion of hot air over global warming marks a new record in the denigration of political language. Behind the overcooked talk about changing the world and saving the planet, the crusade against global warming represents the latest stage in the politics of low expectations and small-mindedness. And far from climate change being a battlefield for any big political ‘war’, the issue is being used to confine debate to an even narrower, more conformist strip of ground.

We have been told many times by political leaders that ours is the era when ‘choice’ is king. Now we can see what they meant. We can choose any shade of politics we like, just so long as it is green. This fits into the pattern of what they call ‘informed choice’, whereby we are expected to make the choices that they inform us are the correct ones.

If we hope to live in a democratic society, any attempt to limit political debate or banish alternative views must be seriously put to question. And there are good reasons for questioning this new political consensus that are quite separate from any debate about the science of climate change. First because, despite the bold talk of all the party leaders, it represents the abdication of political leadership. And second because it reflects an underlying anti-humanist mood in public life. ...

...With their public standing at an all-time low, politicians are attracted to the issue of climate change because it allows them to scramble out of the mire and back on to the moral high ground. Rather than fending off endless allegations of sleaze or trying to explain why they cannot run a decent health service, Blair and Brown are set free to make portentous speeches about saving the planet. And instead of tackling the tricky issues of coming up with alternative policies on the economy or Iraq, Cameron can strike statesmanlike poses while hugging a glacier.

Blair’s remarks this week hinted at how he has suddenly seized upon the global warming issue to provide an ersatz sense of mission for his faltering government. ‘People that have been in Downing Street over the years have faced issues to do with the Cold War, the Depression and the rise of fascism’, the prime minister told a group of teenagers. ‘Climate change is a bit of a different type of challenge, but a challenge I believe is the biggest long-term threat facing our world.’ By recasting climate change as a sort of Nazi or Soviet threat facing the current generation of leaders, Blair elevates himself on to a higher plane of history.

The rise and rise of the politics of global warming also reveals another big problem with leaders today. Lacking any of the political authority of their predecessors, they are continually looking for something else to lean on as a source of public legitimacy. Here they have sought to latch on to the science of climate change. They are dragging scientists on to the stage to try to justify their own petty authoritarian policies, in an echo of the way that the tobacco industry once used men in white coats to advertise its wares....

...Let us leave aside for now the vexed and complex question of the actual science of climate change. I am no climatologist, but then you surely do not need to be to see that the simplistic, conformist politics of global warming are about something else. Even if we were to accept that some of the far-reaching expert predictions about climate change were true, there would be no necessary straight line from those scientists’ estimates to the sort of policies now being proposed by Brown or David Miliband or Cameron. Instead, they are using the language of science to express their own politics of low expectations and policing our behaviour. ...
